.IPEGIFICATION forming part of Letters Patent No. 672,462, dated. April 23, 1901.

Application filed July 16, 1900. Serial No. 23,811- (No model.)

To all whom it may concern:

Be it known that 1, PAUL THGMKE, a subject of the Emperor of Germany, and a resident of Lodz, Russia, have invented certain new and useful Im provements'in Lubricating- Bearings, of which the following is a specification.

My present invention relates to lubricating-bearings, the object being to provide a device of this kind of simple, substantial, and inexpensive construction and in which the lower bearing-section is provided with a suitable compartment adapted to serve as an oilreservoir or as a-conne'cting-passage communicating with larger oil-reservoirs arranged at the ends of the bearing.

With this object in view the invention consists of the novel construction and combi nation of parts fully described and claimed hereinafter.

1n the accompanying drawings, forming a portion of this specification, Figure 1 is avertical transverse section of the improved hearing. Fig. 2 is a longitudinal section of same. Figs. 3 to 6 are transverse sectional views showing difierent manners of forming the joints between the bearing-sections.

Like letters refer to like parts throughout all the views.

Referring by letters to the drawings, a represents the outer casing or body of the bearing, made of two parts, and into the central bore of which is inserted the brass bearingbox I), also made of two parts of cylindrical form. The upper section of the brass bearing is provided at its upper surface with an upwardly-projecting lug 0, adapted to engage a corresponding recess provided in the inner surface of the cap or gland of the bearing for the purpose of preventing the bearingsection from rotating in the main body. In order to prevent axial movements of the bearing-sections, the latter are provided with annular flanges d, and seating parts of the bearing-sections and the main body do not correspond to each other, as the bore which receives the shaft, (250., is arranged eccentrically in the bore of the main body of the bearmg.

It will be seen that by the above construction the normal more or less complicated means for preventing the accidental movements of the several parts and for securely holding same together may be dispensed with. The lower bearing-section b is recessed, as at f, so as to form an oil-reservoir, which extends upwardly at both ends of the bore e of the bearing-sections, so as to be enabled to collect the oil which drops from the shaft at these points. The upper bearing-section b is provided with semicircular grooves a, into which are introduced suitable lubricating-rings 2', the lower parts of which extend into the oilreservoirf, while the upper parts of said rings rest on the shaft journaled in the bearing, the said bearing being strengthened by ribs g.

From the above-described construction it will be readily understood that the oil or other lubricating material cannot be forced or thrown through the open spaces between the lower and upper parts of the main body of the bearing, as the oil-reservoir is provided within the brass bearing, whereby the oil dropping from the shaft'is always thrown against the side walls of said oil-reservoir.

In Figs. 1 and 2 of the accompanying drawings the secting or adjacent surfaces of the brass bearing-sections are in a horizontal plane. However, these surfaces may he stepped or inclined as desired (see Figs. 3 to 6) without departing from the scope or sacrificing any of the advantages of the invention.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a bearing of the class set forth, the combination with the outer or main body made of two parts, of the inner brass bearing box having an eccentric bore, and formed of two sections, and having a suitable recess provided in the lower section and serving as an oil-reservoir, and means for bringing the oil from said reservoir to the shaft journaled in the bearing, substantially as set forth.

2. In a bearing of the class set forth, the combination with the outer or main body made of two parts, of the inner brass bearingbox having an eccentric bore and formed of cess provided in the lower section, substan'- two sections, and having a suitable recess tially as and for the purpose set forth. 10 provided in the lower section and serving as In testimony whereof I have hereunto set an oil-reservoir, semicircular passages being my hand in presence of two witnesses.
